If you were in New Orleans, Louisiana this last weekend, then you might’ve seen hundreds of people wearing red dresses to take part in the Red Dress Run, an annual charity run where participant jogs a short distance from Crescent Park into the French Quarter, the hub of New Orleans nightlife, filled with live bands, amorous drunks and, this weekend, tons of cute guys crossdressing in red.

The event is put on annually on the second Saturday in August by the New Orleans Hash House Harriers. a local group that calls itself “drinking club with a running problem.”

The Harriers, which have local groups all over the U.S. typically combine their running meet-ups with a good bit of drinking. As such, most of the Red Dress Run involves people in dresses carrying plastic cups filled with booze as they run towards the finish lines. And after they’re done running, they drink. (Why can’t we incorporate this idea into the Summer Olympics?)

While it’s unclear how many people participated in this year’s Red Dress Run, the 2017 had about 4,000 people in red-dresses raising $169,000 for various local charities, according to nola.com.

The Red Dress Run reportedly originated in Long Beach, California back in 1987 when a woman in a red dress attended a meeting of the Hash House Harriers. She apparently left such an impression that the runners decided to hold an event with everyone dressing in red the following year.
